To the best knowledge of the Reporting Persons, none of the entities or 
persons identified in this Item 2 has, during the past five years, been 
convicted of any criminal proceeding (excluding traffic violations or similar 
misdemeanors), nor been a party to a civil proceeding of a judicial or 
administrative body of competent jurisdiction and as a result of such 
proceeding was or is subject to a judgment, decree or final order enjoining 
future violations of, or prohibiting or mandating activities subject to, 
federal or state securities laws or finding any violation with respect to such 
laws.

Item 3.  Source and Amount of Funds or Other Consideration
----------------------------------------------------------

The source of funds for the purchases of securities was the working capital 
of Blum L.P.'s limited partnerships and investment advisory clients and 
each of the partnerships for which Blum GP II serves as the sole general 
partner and managing limited partner.


Item 4.  Purpose of Transaction
-------------------------------

The purpose of the acquisition of the Common Stock is for investment, and the 
acquisitions of the Common Stock were made in the ordinary course of business 
and were not made for the purpose of acquiring control of the Issuer.

Although no Reporting Person has any specific plan or proposal to acquire or 
dispose of the Common Stock, consistent with its investment purpose, each 
Reporting Person at any time and from time to time may acquire additional 
Common Stock or dispose of any or all of its Common Stock depending upon an 
ongoing evaluation of the investment in the Common Stock, prevailing market 
conditions, other investment opportunities, liquidity requirements of the 
Reporting Persons and/or other investment considerations.

Also, consistent with the investment purpose, the Reporting Persons may 
engage in communications with one or more shareholders of the Issuer, one or 
more officers of the Issuer and/or one or more members of the board of 
directors of the Issuer and/or one or more representatives of the Issuer 
regarding the Issuer, including but not limited to its operations.  The 
Reporting Persons may discuss ideas that, if effected may result in any 
of the following: the acquisition by persons of additional Common Stock of 
the Issuer, an extraordinary corporate transaction involving the Issuer, 


CUSIP NO. 29481V108            SCHEDULE 13D                     Page 9 of 11


and/or changes in the board of directors or management of the Issuer.

Except to the extent the foregoing may be deemed a plan or proposal, none 
of the Reporting Persons has any plans or proposals which relate to, or could 
result in, any of the matters referred to in paragraphs (a) through (j), 
inclusive, of the instructions to Item 4 of Schedule 13D.  The Reporting 
Persons may, at any time and from time to time, review or reconsider their 
position and/or change their purpose and/or formulate plans or proposals with 
respect thereto.

Item 5.  Interest in Securities of the Issuer
---------------------------------------------

(a), (b) According to the Issuer's most recent Form 10-Q, there were 
51,415,684 shares of Common Stock issued and outstanding as of 
October 29, 2004.  Based on such information, after taking into account the 
transactions described in Item 5(c) below, the Reporting Persons report 
beneficial ownership of the following shares of Common Stock:  (i) 1,586,000 
shares of Common Stock held by Blum L.P. and RCBA Inc. on behalf of the 
limited partnerships for which Blum L.P. serves as the general partner, or on 
behalf of an entity for which Blum L.P. serves as investment advisor, which 
represents 3.1% of the outstanding shares of the Common Stock; (ii) 1,672,900
shares of the Common Stock held by Blum GP II on behalf of the limited 
partnership for which it serves as the general partner and on behalf of the 
limited partnership for which it serves as the managing limited partner, 
which represents 3.3% of the outstanding shares of the Common Stock; and 
(iii) 43,300 shares of the Common Stock that are legally owned by The Nuclear 
Decommissioning Trust of Dominion Nuclear Connecticut, Inc. ("Dominion 
Connecticut") and 43,300 shares of the Common Stock that are legally owned by 
Virginia Electric and Power Company Qualified Nuclear Decommissioning Trust 
("Virginia Electric")(collectively, the "Investment Advisory Clients"), with 
respect to which Blum L.P. has voting and investment power.  Each Investment 
Advisory Client has entered into an investment management agreement with Blum 
L.P., but neither Investment Advisory Client has any contract, arrangement or 
understanding with the other Investment Advisory Client, or any other 
Reporting Person, with respect to the acquisition, ownership, disposition or 
voting of any shares of the Common Stock.  Each Investment Advisory Client 
disclaims membership in a group with any Reporting Person or with the other 
Investment Advisory Client, and each disclaims beneficial ownership of any 
shares beneficially owned by the Reporting Persons other than for their own 
account.

Voting and investment power concerning the above shares are held solely by 
Blum L.P. and Blum GP II.  The Reporting Persons therefore may be deemed 
to be members in a group, in which case the group would be deemed to have 
beneficial ownership of an aggregate of 3,345,500 shares of the Common Stock, 
which is 6.5% of the outstanding Common Stock.  As the sole general partner 
of Blum L.P., RCBA Inc. is deemed the beneficial owner of the securities over 
which Blum L.P. has voting and investment power.  As Chairman, director and a 
substantial shareholder of RCBA Inc., Richard C. Blum might be deemed to be 
the beneficial owner of the securities beneficially owned by RCBA Inc.  
Additionally, Mr. Blum may be deemed to be the beneficial owner of the 
securities over which Blum GP II has voting and investment power. 

Although Mr. Blum is joining in this Schedule as a Reporting Person, the 
filing of this Schedule shall not be construed as an admission that he, or 

CUSIP NO. 29481V108            SCHEDULE 13D                     Page 10 of 11


any of the other shareholders, directors or executive officers of RCBA Inc., 
managing members and members of Blum GP II, is, for any purpose, the 
beneficial owner of any of the securities that are beneficially owned by 
RCBA Inc. or Blum GP II.

c) During the last 60 days, the Reporting Persons purchased the following 
shares of Common Stock in the open market:
